The fatty acid patterns of total serum lipids in the blood of 15 mothers and the mixed cord blood of their newborns were determined by gaschromatography, and the results compared. It is known that the placenta maintains a concentration gradient for lipids between maternal and fetal blood. Quantitative results are given for the total lipid content of the two compartments. The fetal total lipid content was only about one quarter of the mother's. The fatty acid patterns differed characteristically as well, mainly with regard to the concentration of the essential linoleic and arachidonic acid. The linoleic acid level in the maternal blood was high, but low in the mixed blood of the umbilical cord. This was contrasted by low maternal and high fetal levels of arachidonic acid. The placental fatty acid composition was unusual with a 21% content of arachidonic acid. Feeding of a partially-adapted baby food formula resulted in a gradual rise of linoleic acid levels reaching those of adults at the age of 4-9 months.
通过气相色谱法测定了15位母亲血液中总血清脂质的脂肪酸模式及其新生儿混合脐血的脂肪酸模式，并对结果进行了比较。已知胎盘维持着母体和胎儿血液之间脂质的浓度梯度。给出了两个隔室总脂质含量的定量结果。胎儿的总脂质含量仅约为母亲的四分之一。脂肪酸模式也有显著差异，主要体现在必需亚油酸和花生四烯酸的浓度方面。母体血液中亚油酸水平较高，但脐血混合血中较低。相反，母体花生四烯酸水平较低，胎儿水平较高。胎盘的脂肪酸组成不同寻常，花生四烯酸含量为21%。喂养部分适应的婴儿食品配方导致亚油酸水平逐渐上升，在4至9个月大时达到成人水平。
